How to Transfer a Vehicle Title in Wisconsin
The buyer must submit the assigned title, bill of sale, completed MV1 application, proof of insurance, and an emissions test (in applicable counties) at a DMV service center within 30 days. A 5% sales tax applies.
Pro Tip
Complete the bill of sale at the same time the title is signed over. Having both documents ready together prevents trips back and forth to the WI DMV.
Notarization Requirements
Wisconsin does not require notarization for a standard bill of sale. The document is considered valid once both the buyer and seller have signed it. This means you can complete the transaction without scheduling a separate notary appointment, saving both time and money.
That said, you may still choose to have the bill of sale notarized voluntarily. A notarized document carries additional weight in the event of a legal dispute, and some buyers or sellers prefer the added assurance for high-value transactions.
